OF BELLEVILLE, ILLINOIS, A CORPORATION OF DELAWARE DOOR FOR STOVES Application filed March 12, 1931.

This invention relates to doors for stoves; and has special reference to the hinges for supporting the doors in connection with the -stove structure.

it An object of the invention is to provide an improved'hinge for use in supporting doors in connection with a stove wall comprising hinge elements adapted to extend through .holes in the stove wall and to be secured in 1*!) such position, in combination withhinge elements supported by the door and extending through holes in the outer ends of the first hinge elements so as to support the door for i swinging movements.

Another object of the invention is to provide an improved hinge of the type herein disclosed and capable of the advantageous uses to which the device may be applied, ref- --ierencenow being 'madeto the accompanying "drawings, in which Fig. 1 is an outer side elevation of a door mountedin connection with a door frame by means of the hinges that are the subject of the f ,present invention.

Fig. 2 is an inner side elevation of'the door with'partsbroken away to showthe relationship of the hinges.

Fig. '5 is an enlarged horizontal sectional -view of the door frame, a portion of the door 'being shown in open positionand supported by the hinge.

Fig. 6 is a sectional View approximately on,

the line 66 of Fig. 5.

Fig. 7 is a sectional view of the door ap proximately on the line 7 -7 of Fig. 5.

Fig. 8 is a perspective view of one-of the hinge members.

Fig. 9 is a perspective view of. a spring bracket attached to the door for connection 5 with a spring to resist opening of the door, and provided with an abutment to engage a portion of the stove to support the door in a horizontal position. The doorframe 1 constitutes a part of the stove structure and has an opening there- Serial No. 522,016.

through which is opened and closed by the door supported by my improved hinges. The door comprises a frame 2 and a panel 8. In closed position, the frame 2 engages against marginal portions of the frame 1 around the opening that is to be opened and closed by the door.

Each lower corner of the frame :2 is formed with a lug 4 spaced from the marginal flange 5 of said frame 2. The flange 5 and the lug at have alined openings therethrough designed and adapted to receive the hinge pins comprising the stems 6 and heads 7.

The cooperating hinge members comprise pins 8 mounted in holes in the frame 2 and having circumferential flanges 9. that abut against the outer surfaces of the frame Pins 10 are engaged in holes in the inner portions of the pins 8 and bear against the inner surfaces of the frame 2. Thus, the abutment flanges 9 and the pins 10, by ongagement against the outer and inner surfaces respectively of the frame 2, hold the hinge pins 8 in rigid connection with said frame 2.

The outer ends of the pins 8 extend be tween the lugs 4 and the marginal flange 5 at the lower corners of the door, and have holes 11 through which the hinge pins 6 extend. Thus, the door is pivotally supportso ed at its lower corners, because the hinge pins 6 are in axial alinement with'each other, thereby permitting the door to swing to its different adjustments.

Spring brackets are attached to the lower corners of the door for connection with springs which assist in controlling'the opening and closing of the door. Each bracket comprises a base 12 recessed in its outer side to receii e lugs 13 rigid with the frame 2 of the door. Screws 14 pass through the base 12 of the bracket and engage in threaded holes in the lugs 13. Thus, the lugs 13 support the weight of the door when the door is supported by the brackets, the screws 14c serving to hold the brackets in engagement with said lugs. The heads of the screws 14- are on the inside and the stems of the screws do not extend entirely through the frame 2 of'the door, but are embedded therein and are invisible, thus obtaining a more ornamental and pleasing effect than would be obtained if said screws extended entirely through said frame 2.

7 From each bracket base 12, a bracket arm 15 projects downwardly and inwardly and is formed near its inner end with an abrupt shoulder 16. The arms 15 extend through holes 17 in the frame 1 and are free 1y movable through said holes '17. The shoulders 16 abut against the upper marginal portions of the frame 1 around the holes 17 when the door is in an outward horizontal position, thus cooperating with the improved hinges above described to control the door.

In this horizontal open position of the door,

the entire weight of the door is supported by r the brackets 1215, to which the weight of the door is applied by the lugs 13 engaging in the recesses in the'bases 12 of said brackets. j p Each bracket arm 15 hasa headed pin 18 projecting therefrom and forming a connection for one end of a spring 19. The opposite end of the spring 19 is connected to a rigid part 20 of the stove, so that said springs must be extended when the door is opened Accordingly, the power of said springs is utilized to resist the opening of the door and to assist the closingof the door.

'Ea ch bracket base 12 is formed with an elongation 21 curved to provide a notch into which the end of the adjacent hinge pin 6 extends. The adjacent end of said hinge pin 6 isbent, as indicated at 23 (Fig. 7) so as to extend the end 23 of said pin outwardly toward the frame 2 and from the brack et elongation 21. The wall of the notch 22 is adjacent to the pin 6 andthus makes it impossible for said pin to turn entirely about. its axis, thus substantially holding the pin in the position and adjustmenttin which it is initially placed. The bent endl23, of the pin 6 prevents outward movement of said pin while the head 7 limits inward movement of the pin. However, the hinge pin 6 can be removed by straightening the bent 7 end 23 whenever it is desired to remove the door from its hinges. 7,

It is now clear that my improved hinge serves all of its intended purposes in a highly satisfactory manner. The parts areassembled and combined in an eilicient cooper- 1 invention.
